MPLX LP Boosts Quarterly Distribution

MPLX LP (NYSE: MPLX), a prominent US-based master limited partnership known for its midstream energy infrastructure, is making headlines with its latest announcement of a quarterly cash distribution. On October 28, 2025, the board of directors of MPLX's general partner declared a cash distribution of $1.0765 per common unit for the third quarter of 2025. This amount corresponds to an annualized figure of $4.31.

This latest distribution signifies a notable 12.5% increase from the second quarter of 2025, where the distribution stood at $0.96 per unit, marking an increase of $0.12 per common unit. For investors and unitholders, this is excellent news as it reflects the company’s commitment to return value to its investors. The scheduled payment of this distribution will occur on November 14, 2025, benefiting common unitholders who are on record as of November 7, 2025.

Qualified Notice for Non-U.S. Investors

In tandem with the distribution announcement, MPLX has issued a qualified notice to brokers and nominees about the tax implications for non-U.S. investors. According to Treasury Regulation Sections 1.1446-4 and 1.1446(f), brokers must treat all MPLX distributions to foreign investors as effectively linked to a trade or business in the United States. Therefore, there will be a requirement for these distributions to be subject to federal income tax withholding at the highest applicable rate. MPLX emphasizes that it is the responsibility of nominees, rather than the company itself, to handle withholding for the distributions received on behalf of non-U.S. investors.
